Wells score or criteria: (Possible score −2 to 9)

In those with suspected Deep Venous Thrombosis (DVT), a clinical assessment of probability can be useful to determine which tests to perform. The most studied clinical prediction rule is the Wells score.

CRITERIA POINTS
Active cancer (treatment within last 6 months or palliative) YES NO
Calf swelling ≥ 3 cm compared to asymptomatic calf (measured 10 cm below tibial tuberosity) YES NO
Swollen unilateral superficial veins (non-varicose, in symptomatic leg) YES NO
Unilateral pitting edema (in symptomatic leg) YES NO
Previous documented DVT YES NO
Swelling of entire leg YES NO
Localized tenderness along the deep venous system YES NO
Paralysis, paresis, or recent cast immobilization of lower extremities YES NO
Recently bedridden ≥ 3 days, or major surgery requiring regional or general anesthetic in the past 12 weeks YES NO
Alternative diagnosis at least as likely YES NO
WELLS Score =
0-2 LOW RISK - GET D DIMER, +GET USS , ≥2 HIGH RISK - GET USS

ADHB DVT guideline

  • Wells less than 2 get D Dimer - if positive get ultrasound
  • Wells more than 2 get ultrasound
